Law enforcement said Thursday they are confident two bodies found by hunters in a Bremer County park earlier this week are those of Lyric and Elizabeth. There has not been an official confirmation yet from the State Medical Examiner's Office.

Reggie Hovenga, the Care and Outreach Pastor at Heartland Vineyard Church in Cedar Falls, said Friday the service already had been planned to recognize the five-month mark of the date the girls disappeared. Now it will serve as a celebration of Elizabeth's life.

Lyric and Elizabeth's grandmother reported seeing them on their bicycles about 12:15 p.m. on July 13. Those bikes and Elizabeth's purse and cellphone were found about four hours later along a recreational trail at nearby Meyers Lake. Lyric was 10 at the time; Elizabeth was 8.

The investigation is still classified as an abduction, though it could soon change to a double homicide, Abben said at a Thursday news conference.

"I would say that we're looking that way at this time," Abben said. "We have two bodies, but we're going to rely on the state medical examiner to tell us what they think."

In the months since the girls vanished, Heartland and its sister church Countryside Vineyard in Evansdale where Lyric and her mother Misty Cook-Morrissey are members, have served as gathering spots for family and friends to pray and show support for one another.

Misty and Elizabeth's parents, Drew and Heather Collins, have continued to cite their faith in God as a strong form of support and comfort as they've dealt with the disappearance and death of their daughters.

"‚?¶we know our girls our dancing up with our savior. We know that he will continue to be with us giving us strength and comfort always," Heather Collins wrote in a message posted to Facebook earlier this week.
